Application filed January 16, 1905. Serial No. 241,375.

To all when?, it 'm/(ty/ cmi/cern:

Be it known that l, @Liver-i CLARK KineeAID, a citizen of the United States, residing at lFairmont, in the county of Marion and State et' West Virginia, have invented a new and useful Automatic-Valve Trap, oi' which the following' is a specilication.

lhis invention relates to automatic-valve traps `for bath-tubs, lavatories, sinks, and the like; and it has among its objects to improve and to simpli'ly the construction and operation of this class of devices, to insure the automatic opening,l and closing' of the valve members at the proper times, to provide a construction whieh is not liable to become obstructed or impeded by 'foreign siflbstances, and to provide a construction whereby a single standard sii/.e valve will be applicable to various fixtures, as above indicated.

11With these and other ends in view, which will readily appear as the nature el the invention is better understood, the same consists in the improved construction and novel arrangement and combination or' parts, which will be hereinafter `fully described, and particularly pointed out in the claims.

ln the accompanying` drawings has been illustrated a simple and preferred 'form et embodiment of 'the invention, it being, however, 'understood that no limitation is necessarily made to the precise structm'al details therein exhibited, but that the right is reserved to any cl'ianges, alterations, and modilications to which recourse may be had within the scope o'I the invention and without departing` lirom the spirit or sacrificing the eiiiciency ol the saine ln said drawings, Figure l is a vertical sectional view showing the invention applied in operative position to a bath-tub. Fie'. 2 is a side elevation, partly in section, showing the application oli the invention to a lavatorybowl. Fig. 3 a side elevation, partly in section, illustrating` the application ol the invention to a sink or similar lixture. lfig. el is a bottom plan view oli the valve-casina' with one elAL the valve members in position and the other valve member removed. Fig. 5 is a perspective detail view oi' the annular counterweight ilor retaimng' the valve members in a closed position.

Fie'. 8 is a side view ol the same, taken at right angles to Fig'. 7.

Corresponding' parts in the several figures are ind ieated throughout by similar characters o'lf reference.

The valve-easing,l l ci' the device is provided at its upper end with internally-threaded bores 2 3 oi' dil'lierent diameters7 the upper bore 2 beingoln'iously lthe largest. 'iaid valvecasing` also has an externally-threaded portion Ll for connection with a reduction-casing' 5, within which the lower portion ol,l the valvecasing' is accommodated and the' lower end olf which is internally threaded, as shown at l5, Ior connection with the waste-pipe. The valvecasinp; below its externally-threaded portion Ll:

reduced in diameter and is provided with oppositely-disposed vertical flanges or webs T Y, adjacent to which notches 8 are formed in the lower edge oi the casing'. The ialve is composed ot' two members 9 9, combining to `lorm an approximately semispherical cup adapted to :term a tight closure ilor the lower end oi the longitudinal bore Il() ol: the valve-casing'. The valve members are provided with ears or lugs .il ,straddlingthe [langes 7, with which they are pivotallyconnected by means oli pinsllQ. iriaid ears or lugs are accommodated in the notches 8 atlthe lower edge ol the valve-casing', and said valve members are provided below said ears or lugs with outwardly-extendinp' lateral jliang'es 13, serving' to support a ring' or annulus `ll, which is sliding'ly mounted exterior-ly upon the valve-casing' and which constitutes a weight, which by impine'ing' upon the flanges 13 at the outer ends ol the valve members serves to keep the latter normally in a closed position. The annular weicht la, as will be best seen in Fig'. 5 ol the drawing-s, is provided upon its inner side with recesses l5 l'or the accol'nmodation ol the pivotal ears olE the valve members, and it is also provided with notches, as 1G, engaging the web T ol' the valve-easing', upon which the said weight is thus guided without danger oll displacement.

'lhe valve-casing l ,with its related parts, and the redtuition-casingl are always used in confil nection with each other, the reduction-casing l sure, and a slidable member guided upon the constitutingl a protective cover for the operative parts of the valve, which may, however, be readily disassembled from the valve-casing proper for the purpose of affording' access when necessary to the parts of the valve.

The valve device may be litted to various fixtures by means which will now be described.

When the device is to be used in connection with a bath-tub, a pipe-section 18, having a lateral threaded opening 19 for the reception of the overflow-pipe 20, is threaded into the bore 2 of the valve-casing, the upper edge of the pipe-section 18 abuts against the under side of the bath-tub 21, a washer 22 of flexiblematerial being interposed for the purpose of insuring a tight joint. The upper end of the pipe-section 18 is interiorly threaded for the reception of the plug-seat 28, by tightening which the parts will be securely drawn together. The plug-seat has been illustrated as being provided with the usual cross-bars 25, constituting a strainer, and it has further been shown as provided with lateral openings 24 to assist in permitting the water to flow freely therethrough from the tub.

In applying the device to a lavatory-bowl, which has been indicated at 26 in Fig. 2 of the drawings, the pipe-section 18 is dispensed with and the plug-seat 23 is threaded directly :into the bore 3 of the valve-casing, the dimensions of the parts being obviously gaged with this end in view. In this case a washer, as 27, is interposed between the bowl 26 and the upper edge of the valve-casing.

In the application of the invention to a sink, urinal-bowl, or similar fixture, which has been indicated at .28 in Fig. 3, a strainer 29 is provided, which is threaded directly into the bore 2 of the valve-casing, between which and the bottom ofthe fixture a washer 30 is interposed.

In any of the various forms of the device the fixture is preferably provided with an annular recess or seat, as 31, for the reception of a flange, which upon the plug-seat has been designated 32, while upon the strainer the said flange is designated 33.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. The weight of the annulus 14 is suflicient to retain the valve members normally in a closed position. The weight of water impinging upon the upper sides of the valve members will tend to swing said members open apart from each other, thus permitting the passage of the water, the valve being instantly and automatically restored to normal closed position as soon as the water has passed.
